LED Christmas light

Abstract

The present invention discloses a Christmas LED light comprising a lens having an LED light inside the lens, and the LED light having a positive lead and a negative lead fixed on a bottom surface of the LED light; a sealing block is bonded to a bottom of the lens, and lower ends of the positive lead and negative lead each penetrating through the sealing block to reach beyond a bottom of the sealing block; the positive lead and negative lead each are bent to form a bending angle A near the LED light, and light emitted from a light-emitting surface of the LED light illuminates toward a top of the lens to avoid light shadows, and two LED chips in a cavity are reverse-parallel connected to the positive lead and negative lead, so that regardless of the polarity of the external power supply, one of the two LED chips emits light.

What is claimed is: 
     
       1. A Christmas light-emitting diode (LED) light, comprising a lens having an LED light inside the lens, and the LED light having a positive lead and a negative lead fixed on a bottom surface of the LED light; a sealing block fixedly bonded to a bottom of the lens, and lower ends of the positive lead and the negative lead each penetrating through the sealing block from top to bottom;
 the positive lead and the negative lead each bent to form a bending angle near the LED light, and the LED light including a light-emitting surface which illuminates toward a top of the lens; 
 the LED light having a cavity inside, and the cavity accommodating a first LED chip and a second LED chip inside, wherein the two of the first LED chip and the second LED chip are reverse-parallel connected, and after being reverse-parallel connected, the first LED chip and the second LED chip have two terminals each respectively fixed to the positive lead and the negative lead. 
 
     
     
       2. The Christmas LED light as claimed in  claim 1 , further having a central axis from the top of the lens to the bottom of the sealing block, wherein the positive lead and the negative lead each extend beyond the bottom surface of the LED light from a first contact point and a second contact point on the bottom surface of the LED light, and a direction of a connection line between the first contact point and the second contact point is perpendicular to a direction of the central axis of the Christmas LED light. 
     
     
       3. The Christmas LED light as claimed in  claim 1 , wherein the bending angle (A) of both the positive lead and the negative lead is from 70° to 85°. 
     
     
       4. The Christmas LED light as claimed in  claim 1 , further having a central axis from the top of the lens to the bottom of the sealing block, wherein, at a top of the sealing block there are a third contact point and a fourth contact point, and the positive lead passes through the third contact point, the negative lead passes through the fourth contact point, and the third contact point and the fourth contact point are symmetrically disposed relative to the central axis. 
     
     
       5. The Christmas LED light as claimed in  claim 1 , wherein at a top of the sealing block, a ring insert is fixed thereto, and a ring groove matching the ring insert is provided on a bottom end surface of the lens, and the ring insert is inserted in the ring groove. 
     
     
       6. The Christmas LED light as claimed in  claim 5 , wherein the ring insert is provided with a respective limit block on each of two sidewalls of the ring insert, and the ring groove is provided with a respective limit slot matching the limit block, on each of two inner sidewalls of the ring groove, wherein the limit block is inserted in the limit slot. 
     
     
       7. The Christmas LED light as claimed in  claim 1 , wherein the sealing block is fixedly penetrated through by a plurality of metal thermal blocks from the bottom of the sealing block and into a space inside the lens, and the plurality of metal thermal blocks are interspersed with the positive lead and the negative lead to conduct heat in the lens to an exterior of the lens for heat dissipation. 
     
     
       8. The Christmas LED light as claimed in  claim 1 , wherein an annular recess is provided at an upper section of an outer wall of the lens, and a color paper is attached in the annular recess, and a color of the light emitted from the Christmas LED light is changeable by replacing the color paper with a color paper of a different color. 
     
     
       9. The Christmas LED light as claimed in  claim 8 , wherein the color paper is glued to the annular recess. 
     
     
       10. The Christmas LED light as claimed in  claim 1 , wherein a light diffusion layer is provided on top of the light-emitting surface of the LED light.
